Answer:
Step-by-step explanation:
Vertex form of a quadratic is given by:
Where (h, k) is the vertex and <em>a</em> is the leading coefficient.
We are given that the vertex is (3, 1). Hence, <em>h</em> = 3 and <em>k </em>= 1. By substitution:
We are also given a point (2, -6). This means that when <em>x </em>= 2, <em>f(x)</em> = -6. Hence:
Solve for <em>a</em>. Subtract:
Simplify:
Therefore:
Hence, our quadratic is:
Any function is also a relation. The function shown in the graph can be described by ...
C. both a relation and a function

Step-by-step explanation:
Domain means X. So you look for the smallest X value in your data and the largest X value in your data.
Answer:
H0 : μ = 0.75
H1 : μ > 0.75
Step-by-step explanation:
Given :
Sample size, n = 125
x = 99
Phat = x / n = 99 / 125 = 0.792
Population proportion, P = 0.75
The hypothesis :
Null hypothesis :
H0 : μ = 0.75
Alternative hypothesis ;
Egates the null hypothesis ; since the sample proportion is greater than the the population proportion or claim "; then we use the greater than sign.
H1 : μ > 0.75
Answer: 1,004.8 cubic meters (choice D)
Work Shown:
V = (1/3)*pi*r^2*h
V = (1/3)*3.14*8^2*15
V = 1,004.8
